prototyping - How to fix a 'PCB' without mounting holes inside a case (or on a PCB)?

I want to use several of the 'filled PCBs' below, or other ones, but the question does not change.

How can I fix such thing in a case, or on a proto/veroboard PCB (like the picture below)?

I thought about:

• Glueing: but since the case (including the components) will be moved a lot, it doesn't seem a good way.


• Using tie wraps, in this case it might work because it can be put around the yellow component, but what if I want to use another component that does not have a nice yellow box?


• Using one of the above methods with spacers to prevent contacts with the protoboard.

I don't need a professional solution, but I want a solution that doesn't break or getting loose after being 100 times moved neither.

Update

I asked a similar earlier question. However, this was about a temporary solution, in which I expected components need to be changed/added. However, in this case it's about a fixed/known setup. So I hope that a more professional (or at least 'better') solutions exist.

Answer

Use a box with card guides, (ie grooves in the walls) and fit a PCB card guide

Now the board / boards are horizontal and closing the lid locks everything in place.

Search for "P.C. Board Card Adaptors" or "Allows mounting of PC boards horzontally within the enclosure."
